General information for the installer
FIGHTER 1110
For the Installer
10
Current regulations require the heating installation to
be inspected before it is commissioned. The inspec-
tion must be carried out by a suitably qualified person
and should be documented. The above applies to
closed heating systems. If the heat pump is replaced,
the installation must be inspected again.
FIGHTER 1110 is placed on a firm base, preferably a
concrete floor or foundation. FIGHTER 1110 should
be setup with its rear against an outer wall in a
scullery or similar type of room to eliminate noise
problems. If this is not possible, avoid placing it
against a wall behind a bedroom or other room where
noise may be a problem. Irrespective of the placement
the wall should be sound insulated. Route pipes so
they are not fixed to an internal wall that backs on to a
bedroom or living room.
The FIGHTER 1110 must be transported and stored
upright and dry.

Guideline values for collectors
Inspection of the installation
For use with 40 x 2.4 PN 6.3 PEM hose.
For size 4, 32 x 2.0 PN 6.3 PEM hose.
The length of the collector hose varies depending
on the rock /ground conditions and on the heating
system, i.e. radiators or floor heating.
Max length per collector should not exceed 400m.
Where there is more than one collector, they must be
connected in parallel, with a means of adjusting the
flow.
The hose should be buried at a depth of about 1 metre
and the distance between the hoses should be at least
1 metre. For several bore holes, the distance between
the holes must be at least 15m.

FIGHTER 1110 can be docked with an external unit
with its own automatic heating control system. FIGHT-
ER 1110 then delivers heat up to a fixed temperature
level. This is known as fixed condensing. See docking
options 5 and 6. For setting, see the For the house
owner, Control, Setting of min/max temp, display
mode 5b section. Also see the For the installer sec-
tion, Control, Settings, display mode 10 section.
Reconnection is done according to Electrical connec-
tion, Connecting the brine fluid pump for fixed con-
densing.
See the instructions for the external units for how to
regulate the room temperature.
The outside sensor has no function with this option,
but it should be connected to prevent error messages
appearing on the display. There is no need to install
the sensor outside.
Heat production is usually controlled using the floating
condensing principle. This means that the tempera-
ture level needed for heating at a given outside tem-
perature is produced on the basis of values taken from
sensors for outside temperature and flow temperature
(see docking options 1, 2, 3 and 4). Room sensors
can also be used as an option to compensate for vari-
ations in room temperature.
